Abstract:

 

In this talk, we firstly discuss evolving display trends and the technical demand in the view points of i) high picture quality, ii) free-form factor and iii) expandability of display. Obviously display already uses various materials such as soft matters and also demands high functional materials. However, it should be noted that the unique properties of soft matters from structure change are not fully manipulated yet. In contrast, from the material point view we can imagine various functional photonic applications including display application. Hereto, we discuss soft matters such as polymer and liquid crystals and their intrinsic properties with their structural change against various external stresses. Several pieces of studies, self-organized 1D and 3D chiral photonic band structure (PBS) based soft material are discussed. For high optical functionality, photonic wavelength band tuning from the predefined PBS structure, the stretching deformation and band edging lasing property are also discussed. In further, toward high functional deforming applications, stimulus controllable actuation behaviors of soft material are discussed.
